My wife and I were in Cape Town for our 10th anniversary and decided to go shark cage diving. We researched several companies and settled on ASEC because of the small number of passengers on the boat and the fact that they use SCUBA. The experience was incredible, one that neither of us will ever forget. The seas were choppy that day but we still went out, we had 7 passengers total not including the three crew members. We saw approximately 7-8 sharks and were able to dive twice in the cage. I would highly recommend this company to anyone, ESPECIALLY SINCE THEY DO SCUBA…I can’t imagine trying to do cage diving with a snorkel or just popping up to catch your breath, there is no way you would get the full experience unless you do SCUBA. Thanks to ASEC for an awesome unforgettable experience.
